the harmony remote worked on my LV9500 with the service menu. I bought the Harmony 650 instead of the LG service remote because it can be used as a all around remote, not just on the LV9500.
The people on this forum did a great job on explaining how to use the Harmony 650 remote to gain access to the service menu.

I'd be a bit cautious on proceeding down that path, as our units are supposedly 400Hz, whereas the US ones are 480Hz (I think)? If there is some actual hardware differences, then there could be an issue. I do remember reading either in this LG thread, or another model one, where a user took his US state to the middle east, was prompted to download a new firmware version, and it bricked his TV.

I would personally just calibrate the hell out of it, and enjoy the solid PQ.

Yep, mine appear to lessen after 10'min or so - which makes me think a thermal issue. Called lg support, they said to do a factory reset, which seemed to help, but only I think because my settings were erased and it's back to more of a torch mode and I havnt had time to do a proper calibration again. I've got until November until the warranty runs out, so I'll be chasing it up again late September when I'm back from holidays.

If you game at all, don't download update 04.01.30. The previous update had an average input lag of 43 ms. This new update increased it to an average of 73 ms.

Is there a way to revert to the previous firmware version?

x2. i'm curious if any of the more recent firmware updates have corrected this. Heck, I'm not even sure what input lag is on this set. I know that I just moved my ps3 to this TV from my Panny plasma and the lag is significantly worse. Anybody?

LG service came out today and looked at my panel and the dark lines. Watching ice hockey really showed the lines.
Just got a call from LG service and they said a new panel could not be ordered for the LV9500. He informed me the warranty company would be calling me.
My wife is upset, she liked the picture on the LV9500.
I bought a LG extended warranty for the LV9500 and I'm glad I did.
The LG service repairman said the warranty company would offer me a replacement or a buyout.
Anyone know if it really is LG offering a different TV? The truck was a official LG repair truck, if their is such a thing .
Any idea's on a LG TV to replace my LV9500? Does LG make nano TV'S?

My LV9500 finally stopped working today. The display on the TV stopped working when I hit the connection between my keyboard and its USB extension, which is plugged into my desktop, the only input connected to the TV. Both the TV and desktop share the same UPS. Extremely weird that a USB surge would be able to propagate to the TV and blow some circuitry, but that’s obviously what happened.

It’s worthy to note that the TV stopped displaying a picture when I hit the USB extension/keyboard connection (the USB extension runs across the room), but this was resolved easily with rebooting the desktop. For the past month, I did notice the picture and audio cutting out (at the same time) for ~1 full second, showing a few thin, red, horizontal bands. (I wasn’t certain at the time if this was an issue with the desktop or TV.)

The remote still works to turn the TV off and on. The red LED power-off light is lit when the TV is off. Upon powering the TV on, the aforementioned LED turns white, with all LED white indicator lights to its left lighting up as well (home, input, vol, etc.). I left the TV off overnight and the display continues to not work. After powering the TV off and unplugging it, the red power-off light is still lit for almost a full minute (caps taking time to dissipate). I have tried blindly cycling through the inputs in an attempt to hear the static from the coaxial cable input, to no avail. I attempted to see if the LCD itself is still displaying a picture, without a backlight. I did this in an entirely dark room, by shining a flashlight on the display after pushing the home button. I was not able to see any picture or textures whatsoever. The TV still makes the capacitor single-click noise when turning on and off.

I have yet to take off the backplate and examine it, though I suspect the main board itself is fried. Still trying to diagnose, find the part number of the main board, and hopefully order another one, if it is the culprit.

4.5 years is not nearly as long as I would like a flagship TV to last (I was hoping for 10), but I am very thankful for all of the insight and support this thread and community has given.

I was hoping to save my money for some studio monitors, to finally get away from TV speakers, but I’ll probably have to get another TV instead. If anyone has any recommendations for a full-array LED TV, 1080p, active 3D, I’m all ears. (A little too much 3D crosstalk in the LV9500 for me.) From what I’ve seen of OLED, it has just broken through its infancy (might be better to hold off for a few more years). 4k would be great, but is not a necessity to me.

Thanks again to nony and everyone here. Your clear, objective responses and comparison the 55LHX were of great help.

My LV9500 screen stared to have dark cloudy lines going from the bottom halve way up the screen that I could see while watching Ice Hockey games. I would hesitate to buy another Lucky Gold Star TV. I think people who had a problem with Vizio TV'S would find a LG panel. I have older LCD TV'S that are still going. I would not buy a OLED at the price LG is charging, I just don't have the money to replace it in three to five years. I am glad I bought a extended warranty for my LV9500.
